The first Indian film, "Raja Harishchandra," was released in 1913, marking the beginning of the Indian film industry. However, it wasn't until the 1950s and 1960s that Bollywood started to gain popularity, with films like "Shree 420" (1955) and "Mughal-e-Azam" (1960) becoming huge successes. These early years laid the foundation for the industry, introducing iconic actors like Dilip Kumar, Dev Anand, and Raj Kapoor.
